-This script patches the CRC checksums into an existing ELF file.
-
-For this, it searches the follwoing sections:
-	1) .text
-	2) .data
-	3) .ccmdata
-	4) .vectors
-
-All sections MUST be a multiple of 4 bytes long because the CRC calculation relies on whole 32 bit words.
-The sections are excrated and the CRC is calculated for each section.
-
-In the section .flashcrc, the script expects a single struct with the prototype:
-struct flash_crcs {
-	uint32_t start_magic;
-	uint32_t crc_section_text;
-	uint32_t crc_section_data;
-	uint32_t crc_section_ccm_data;
-	uint32_t crc_section_vectors;
-	uint32_t end_magic;
-};
-
-It checks, if the start magic and end magic are set to the appropriate values and then patches in the CRC values of the sections.
-The magic values checked for are: 0xA8BE53F9 and 0xFFA582FF
